A Millimeter‐Scale Implantable Magneto–Mechano–Electric Transducer Based on BTO Piezoelectric Ceramics for Remote Wireless Electrical Stimulation of Injured Sciatic Nerves

Advanced Science, EarlyView.
We report a fully wireless, circuit‐free neural stimulator built on a millimetric magneto‐mechano‐electric (MME) cantilever transducer (3 × 10 × 5 mm) with a barium titanate (BTO) piezoelectric ceramic core. Under low‐frequency alternating magnetic fields, the MME cantilever mechanically oscillates, inducing stress on the BTO element and thereby ...

Ischaemic stroke as the initial presentation of a pheochromocytoma associated with neurofibromatosis type 1

Asian Journal of Internal Medicine
Pheochromocytoma is a rare but well-recognised manifestation of neurofibromatosis type 1 (NF1). Ischaemic stroke has been rarely reported in patients with pheochromocytoma. It can be due to either hypertension or vasospasm. A 33-year-old woman presented

Pheochromocytoma and heart rate variability: a systematic review and meta-analysis

International Journal of Cardiology. Cardiovascular Risk and Prevention
Introduction: Pheochromocytoma is a catecholamine-producing tumor, that may alter cardiovascular activity. Conveniently, sympathovagal activity can be measured non-intrusively and pain-free through heart rate variability (HRV).

Pheochromocytoma: Yes or No? [PDF]

Clinical Chemistry, 2014
A 76-year-old woman was admitted for cardiac decompensation, hypertension, and renal failure. To explore her chronic hypertension, urinary fractionated metanephrines were quantified. Fig. 1A shows the chromatogram of the patient's urine, and Fig. 1B shows the chromatogram of a calibration standard. A very large methoxytyramine …

Carbon Dots for Cancer Theranostics: Synthesis Strategies, Luminescence Properties, and Advances in Bioimaging‐Guided Diagnosis and Therapy

Chemistry – A European Journal, EarlyView.
Lighting up the path to precision oncology: This review comprehensively summarizes the rational design of carbon dots (CDs), elucidating how core size, surface chemistry, and heteroatom doping dictate their luminescence mechanisms. Special emphasis is placed on engineering NIR‐II emissive CDs for deep‐tissue imaging.
